Iteyiphu yefilimu yePPFO , ebizwa ngokuba yi-PPFO yefilimu yefilimu okanye i-teflon tepe, idume ngokukodwa ukumelana nobushushu bayo. Izinto eziguquguqukayo zinokukhusela ubushushu obuphakamileyo, zenza ukuba zibe yinto ebalulekileyo kwizicelo ezahlukeneyo zemveliso. Iteyiphu yefilimu yePPFO ihlala igcina ingqibelelo yakhiwo kunye nentsebenzo kumaqondo obushushu ukuya kwi-260 ° C Oku kuchaswa kobushushu obumangalisayo kungenxa yesakhiwo esikhethekileyo sekhemikhali se-PTFE, esihlala sizinza phantsi kweemeko ezigqithisileyo. Ngenxa yoko, iteyiphu yefilimu ye-pmpfe iba sisisombululo sokutywina kobushushu obuphezulu, ukufakelwa, kunye nokukhuselwa kumashishini asusela kwi-aerospace ukuya kuqhubekeka nokuqhubela ukutya.

Isayensi emva kobushushu be-ptfe yefilimu
Isakhiwo sekhemikhali se-ptfe
I-PTFE, okanye iPolytetrafluorororookene, yi-fluoolly ye-fluoolly ye-tetrafluororororororororororoothyncylene. Isakhiwo saso semolekyuli siquka ii-atoni zekharbon zigcwele iiathom ze-fluorine kwikhonkco elide. Eli lungiselelo likhethekileyo linika i-ptfe ukukhetha uzinzo olukhethekileyo. I-Calbon-Boorine ye-sleorine ifuna amandla abalulekileyo yokuqhekeza, ukuvumela i-ptfe ukugcina iipropathi zayo nakwiqondo lobushushu eliphakamileyo.
Iipropathi ze-thermal yeteyiphu yefilimu ye-ptfe
Itheyiphu yefilimu ye-PPFO ibonisa iipropathi ezibonakalayo eziza negalelo ekusebenzeni kwayo kubushushu obuphezulu. Inengxaki yokuqhubela ephantsi, oko kuthetha ukuba ayiphumeleli ngokulula ubushushu. Olu phawu luyenza i-insulator efanelekileyo. Ukongeza, i-PTFA inomgangatho ophezulu wokunyibilika wama-327 ° C (620 ° F), yaphucula amandla ayo okuxabana nobushushu obugqithisileyo okanye ukuphulukana nepropathi esebenzayo okanye ilahlekelwe ziipropathi ezisebenzayo okanye ezilahlekelwa ziipropathi ezisebenzayo.
Ukuthelekisa nezinye izinto zobushushu eziphezulu
Xa kuthelekiswa nezinye izinto zobushushu obuphakathi, i-PPFO yefilimu ihlala iphungulo kwizinye iindlela ngokwesinga lokuxhathisa ubushushu kunye ne-dicturmic. Umzekelo, iiteyiphu ezisekwe kwi-Silicone ziqhele ukuba neqondo lobushushu e-200 ° C (i-392 ° F), ngelixa ezinye iiteyiphu zePolyomides eziphezulu zinokumelana namaqondo obushushu ukuya kuthi ga kwi-400 ° C (75 ° F). Nangona kunjalo, ukudibanisa kukaPt Peloty yokungaxhathisi ubushushu, ukunganyangeki kwekhemikhali, kunye nokuxabana okuphantsi kwenza ukhetho oluphezulu kwizicelo ezininzi zobushushu obuninzi.
Izicelo zeteyiphu yefilimu yePPFO kwimeko yobushushu obuphakamileyo
Ukutywinwa kwemizi-mveliso kunye nokufakwa
Kwiseto semizi-mveliso, iteyiphu yefilimu ye-pmpfe isetyenziselwa ukutywina kunye nokufakelwa kweemeko zobushushu obuninzi. Ibaluleke kakhulu kwizityalo zokuqhubekisa iikhemikhali, apho isetyenziselwa ukudityaniswa kwe-ping kunye ne-fitlengs evezwe kwiikhemikhali ezinobunzima kunye nobushushu obukhulu. Isakhono seteyiphu sokugcina itywina eliqinileyo phantsi kwale meko kunceda ukuthintela ukuvuza nokuqinisekisa ukhuseleko kunye nokusebenza kakuhle kweenkqubo zokusebenza.
I-Aerospace kunye neMizi-mveliso yeZithuthi
Amacandelo e-Aerospace kunye namacandelo emoto axhomekeke kakhulu kwi -pmpfe tepi yefilimu ye-pmpfe yezicelo ezahlukeneyo zeqondo lobushushu. Kwiinjini zenqwelo moya, i-PPFE TOPI isetyenziselwa ukusongela iingcingo kunye neentambo, ukubonelela ngokufakelwa kombane kunye nokukhusela kubushushu obuqinileyo ngexesha lokubaleka. Ukuqulunqwa kwemveliso yemoto, isetyenziselwa ukhuseleko lobushushu, ukukhusela izinto ezibuthathaka kubushushu beenjini. Iipropathi zeteyiphu eziphantsi zethayile zikwenza ukuba iluncedo ekunciphiseni impahla yokunciphisa iinxalenye ezihambayo zivezwe kubushushu obuphezulu.
Ukulungiswa kokutya kunye nokupakisha
Izibonelelo zoncedo lokutya ezivela kwi-ptfe ye-ptfe i-pmfey tape teicraibrey ye tape tape kunye neepropathi ezinganamava. Kwisixhobo sokulungisa ukutya, ityhefu isetyenziselwa ukuhambisa iibhanti zokuhambisa kunye neebhanti zokutywina koomatshini bokupakisha. Esi sicelo sivumela umsebenzi ogudileyo, ongenazongangangayo nokuba ujonge ukutya okushushu, okunamathelayo. Amandla eteyiti yokumelana namaqondo obushushu aphezulu ngaphandle kokukhupha izinto ezinobungozi aqinisekisa ukhuseleko lokutya kunye nomgangatho kuyo yonke inkqubo yemveliso.
Izinto ezichaphazela intsebenzo yeqondo lefilitha ye-ptfe
Ubukhulu kunye nomgangatho we-ptfeeer
Ubungqingqwa kunye nomgangatho we-ptfeemer ye-ptfele kwitheyiphu iphembelele ngokusebenza kweqondo lobushushu ephezulu. Ngokubanzi, iindawo ze-ptfer ptfeke zibonelela ngokufakelwa okungcono kunye nokuxhathisa ubushushu. Nangona kunjalo, umgangatho wezinto zePTFO ubaluleke ngokulinganayo. Umgangatho wefilimu ephezulu ye-ptfe-ekumgangatho ophezulu we-PPFN kwiTeflon Tape Amed Rape uthatha iinkqubo zokuvelisa ukuqinisekisa ubungqingqwa obungaguqukiyo, kunye nokucoceka. Ezi zinto zinegalelo ekusebenzeni okungaguqukiyo phantsi kobushushu obukhulu.
Uhlobo olunamathela kunye nokuchasana nobushushu
Ngelixa ifilimu ye-pmpfe ngokwayo ixhaphake kakhulu, ukunamathela okunene kusetyenziswa iteyiphu yefilimu ye-pmpfe yimbonakalo kunokuba yinto enokuthi ibe yinto ethintelayo kwizicelo eziphezulu zokusebenza. Amadlala ama-Acrylic esekwe kwinqanaba lerabha okanye amachaphaza asekwe kwirabha anokuqalisa ukungcoliseka kubushushu obuphantsi kunefilimu yePPFO. Kwizicelo ezifuna ukumelana kobushushu obuqinileyo, ezisekwe kwi-salicone ekhethekileyo okanye amanye amaqondo amane amayeza aphezulu asetyenziswayo. Ezi ncwadana zinokumelana nobushushu obufana nefilimu yePPFO, ukuqinisekisa itayipu igcina amandla ayo kunye nengqibelelo ekufumaneni iindawo.
Izinto zokusingqongileyo kunye nexesha lokuvezwa
Ukusebenza kweteyiphu yefilimu yePPFO kubushushu obuphakamileyo kunokuchaphazeleka ngezinto zokusingqongileyo kunye nexesha lokuvezwa. Ukuboniswa ixesha elide kubushushu kufutshane nomda wayo ophezulu kunokukhuphela ngokuthe ngcembe iipropathi zethamsane ngokuhamba kwexesha. Izinto ezifana ne-radiation ye-UV, ukuvezwa kwemichiza, kunye noxinzelelo loomatshini kunokuba nefuthe kwitheyibhile yobomi obude kubushushu obuphakathi. Kubalulekile ukuba uqwalasele ezi zinto xa ukhetha itayiphu yefilimu ye-pmpfe yezicelo kwaye ulandele izikhokelo zoMvelisi weMsebenzini oSebenzayo kunye noLongen.
Ukuqukumbela
Isakhono esimangalisayo se-PPFFFFOICKI YOKUGQIBELA UKUQHUTYELWA KWEXESHA LOKUGQIBELA LENZA ISIQINISEKISO SEZOBUCHULE NGEMALI AMALUNGU. Isakhiwo sayo esahlukileyo, sidityaniswe neepropathi zayo ze-thermal, sivumela ukuba igcine ingqibelelo kunye nokusebenza kwiimeko zobushushu obugqithisileyo. Ukusuka ekutywinwe kwezommiselo kwizicelo ze-aerospace kunye nokulungiswa kokutya, iteyiphu yefilimu ye-pmpfe iyaqhubeka nokungqina ixabiso laso lobushushu obuphakamileyo. Nangona kunjalo, izinto ezifana nomgangatho wetywina, uhlobo lokuthoba, kunye neemeko zokusingqongileyo zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza kwayo. Ngokuqonda le miba, iinjineli kunye nabavelisi banokunyusa amandla apheleleyo e-PPFI yefilimu ye-pmpfe kwizicelo zabo zeqondo lobushushu.
